History
The locality was named and bounded on 27 July 1991.[2] It was presumably named after the now-abandoned Calcium railway station (19°40′32″S 146°50′05″E / 19.6756°S 146.8348°E) on the Great Northern railway,[8] which had been named prior to 1914 after the calcium-bearing lime that was mined in the area.[9][10]
